• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"new science all over\") OR (\"del science book over\"))) OR (\"best science from le\"))~".
• Removing quotes may allow a broader search: (((( new science all over ) OR ( del science book over ))) OR ( best science from le ))~.
• Adding a wildcard symbol may retrieve word variants: (((("new science all over") OR ("del science book over"))) OR ("best science from le"))*.
